摘要：

Advanced oxidation processes provide a destructive, economical alternative to conventional treatment methods for the removal of hazardous organic pollutants from groundwaters and industrial wastewaters. This project investigated the kinetics of trichloroethylene oxidation by ultraviolet light and hydrogen peroxide. The reaction rate of trichloroethylene was first order in ultraviolet light intensity and pseudo first order in trichloroethylene concentration. The rate was first order in hydrogen peroxide concentration at low peroxide levels, but independent of peroxide concentration at high peroxide levels. The maximum rate attainable depended on the reactor depth, with the shallower reactor yielding the larger maximum rate. A mechanism for trichloroethylene oxidation was proposed which yielded a rate expression consistent with the experimental observations.
